Solution Overview

Problem

The challenge lies in developing a compact and aesthetically integrated sensor system for fully or partially autonomous motor vehicles that can reliably recognize environmental situations, withstand external influences, and maintain optimal performance over the vehicle's lifespan, while also being discreetly visible from the outside and adaptable to various driving conditions.

Innovation Solution

A motor vehicle sensor combination module that integrates multiple sensors as a self-contained unit in the vehicle's front area, utilizing adjustment mechanics for static and dynamic settings, with a common reference system for calibration, and a protective housing with a cover window to shield sensors from external factors, including a lighting unit and shock-absorbing components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If multiple sensors are integrated into a central sensor combination module mounted on the vehicle exterior, then the sensor system becomes more compact and aesthetically integrated, but the sensors become more vulnerable to external influences such as dirt and weather

Engineering Contradiction:
Improvesensor system compactnessVSAvoidexposure to dirt and weather
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent integrates multiple sensor devices (cameras, LIDAR, radar) into a nested configuration within a single sensor combination module housing. The sensors are arranged in overlapping or adjacent relationships within the compact housing, allowing them to share the same mounting space while maintaining their individual fields of view and detection capabilities.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent employs a protective housing with a cover window that shields the sensors from external influences. The housing acts as a flexible barrier that protects sensitive optical and electronic components from dirt, weather, and physical damage while allowing electromagnetic waves (light, radar, LIDAR) to pass through to the sensors.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If sensors are placed around the vehicle exterior including on the roof, then the field of view and detection range are maximized, but the sensor system becomes more complex and less aesthetically pleasing

Engineering Contradiction:
Improveenvironmental situation detection capabilityVSAvoidsensor system configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple previously separate sensor devices (front camera, front LIDAR, front radar, and other sensors) into a single integrated sensor combination module. This merging reduces the overall system complexity by consolidating mounting locations, power connections, and data processing interfaces while maintaining the comprehensive environmental detection capability through the coordinated operation of individual sensors within the module.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the sensor assembly is made adjustable and controllable, then the system can adapt to various driving conditions and compensate for dynamic influences, but the device complexity increases

Engineering Contradiction:
Improveadjustment to driving conditionsVSAvoidadjustment mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent incorporates adjustable mounting mechanisms that allow the sensor assembly to change its orientation and positioning dynamically. The sensor holder can be adjusted in angle and position to compensate for vehicle movements, road irregularities, and different driving conditions. This dynamic adjustment capability ensures optimal sensor alignment and field of view while adapting to varying operational requirements.

Inventive Principle:
Principle #15Dynamics
